Abstract

The piping is a corrugated pipe (2) with parallel undulations made from endless or metered lengths which can be cut to the required length and laid in flexible manner. The free ends of the pipe can be flanged over and connected pressure-tight to the ends of further similar pipes or to components of the water supply system by semi-dished threaded members such as flanges or by half rings (30a,30b). The ratio of the lengths of the peaks (4) to the troughs (6) of the pipe is less than 1 or greater than 1. The pipe is made from metal and encased in plastics hose which is preferably fibre-reinforced in the longitudinal direction. The pipe can have a protective lacquer or encased in a shrink-fit plastics hose.
